Jasjar Battery Extender-not working :`(

I purchased the Jasjar battery extender (the one in the link above). And it turned out not working. Instead of charging, it helps drop the Jasjar battery more rapidly. :`( What could be worse than that. See my email threat with the vendor below.

My PDA is imate Jasjar, the one this product is designed for. The name of the product and the image posted in the web store is an imate Jasjar. So, it has to work fine.

I did measure the voltage output of the battery extender and it shows 5.1 - 5.2V which is the good range for charging the imate Jasjar.

I really cannot accept the fact/excuse that there is possibilty my imate Jasjar is not compatible, like you said.

I have tested both battery extenders I have, so they are the same characterics. I do not think even though you send me a new one, it will work out too.

I can only test out the compatibility with imate Jam when I give the second one to my brother. If it does not work out, I can accept that, as it might not tested before with imate Jam, and the product is not listed compatible, at least, even though you have confirmed to me that they should be compatible. But with my PDA, imate Jasjar, I really cannot accept that fact, that instead of charging the device, it consumes the power as well.

Please help report this back to your engineering department, so they can test it more thoroughly and fix the charging/regulator circuit.

>>I would like to let you know that I have performed several more

>>testings on the products I bought from your store, the Jasjar

>>battery extender.

>>And the overall result of my testing proves the battery extender is

>>not working as expected, as published in your web store's

>>description about the product.

>>

>>I used brand new Energizer AA Alkaline batteries. First load, it

>>fails to charge the Jasjar battery. Instead of charging it, it

>>caused the Jasjar battery to drop all the way to 10% few hours

>>later.

>>Second load with brand new battery, before start charging, the

>>battery status was 45%. After charging it for entire night, the

>>next morning it became 5%!

>>The battery extender was not the power supply anymore, it became

>>the load/resistance instead.

>>

>>May I know did you guys really tested this product properly before

>>launching it. I'm really curious.

>>The spec shows really clear, 2.5 times charging capability from a

>>complete discharge. Sorry, really, but i'm really dissapointed,

>>especially I purchased 2 units and just expect them to be working

>>fine.

>>

>>This is from your website:

>>

>>Requires 4 AA batteries, which will charge the PDA roughly 2.5

>>times from a complete discharge.

>>· Charge and use your PDA at the same time.

>>· Special circuitry design protects your PDA from overcharging and

>>short-circuiting

>>· Charges to 45% in 20 minutes

>>

>>I hope you can help me resolving this.

>>

>>Thank you. I got the shipment yesterday and exicted trying it out

>>last night.

>>I try it with my imate Jasjar. Cannot test it with imate Jam as I

>>don't have one, but the second battery extender I ordered was

>>intended for my brother who has a imate Jam.

>>

>>I use 4 AA alkaline batteries (Energizer) and measure the output

>>voltage with a multimeter, it showed 5.2 V, which is good.

>>When I hooked it up to my Jasjar, the charging led started light up

>>as normall.

>>When I start charging it, it was 45% battery remaining. Few hours

>>later, I looked at it, its not fully charged yet, and when I

>>unplugged it and check the Jasjar battery status, it dropped to 5%!

>>Very surprising and I have no clue how could that happens. Without

>>the battery extender, usually without any usage, the Jasjar will

>>only drop 1-2% battery in 4 hours!

>>

>>I will test again tonite. But i ended up charging it with the AC

>>power adapter last night.

>>If you know/have any suggestions, I would like to know. I hope it

>>to be working good to extend the life of my PDA during long flight

>>and I would like to give the same thing for my brother without any

>>disapointment.
